PHOTOGRAPHIC APPARATUS.

EPECIFIGATION forming part of Letters Patent No. 355,084, dated December 28, 1886.

Application filed August 29, 1 885. Serial No. 175,648. (No model.)

To aZZ whom it may concern.-

Be it known that 1, DAVID H. HOUSTON, of Hunter, in the county of Cass and Territory of Dakota, have invented a new and Improved Photographic Apparatus, of which the following is a full, clear, and exact description.

The object of myinvention is to provide certain new and useful improvements in the photographic apparatus for which United States Letters Patent No. 248,179 were issued to me 7 on the 11th day of October, 1881.

The invention consists in parts and details and combinations of the same, as will be fully described hereinafter, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding; parts in all the figures.

Figure l is a longitudinal sectional elevation of my improved photographic apparatus. Fig. 2 is a erosssectional elevation of the same. Fig. 3 is a sectional plan view of the same. Fig. i is a detail plan view of the paper-holding boX, the cover of the same being removed. Fig. 5 is a longitudinal sectional elevation of one of the spools and the sensitized paper or film thereon. Fig. 6 is a longitudinal view of one of the spindles. Fig. 7 is a rear view of the attachment, showing a modified construction of the roller-frame independent of the lighttight case, into which it is placed for use. Fig. 8 is a plan view of the same, the door being closed. Fig. 9 is aplan view, the door being open. Fig. 10 is a eross-sectional view of the roll-frame. Fig. 11 is a longitudinal view of a modified construction of the spindle. Fig. 12 is a plan view of the adjustable collar on the same. Fig. 13 is a cross-sectional view of the spool.

The removable box A,provided with asliding, shutter, A, fits in the rear part of the camera B, and contains the sensitized paper or sensitized film a, which is wound upon two spools, O, mounted to turn in the box or rollholder A, the said film or sensitized paper a being also passed over rollers D, so that a straight part of the said sensitized film or paper passes over a plate or partition, E, directly behind the sliding shutter A. By raising the shatter the film or paper a is exposed to the spool and exposed, and so on.

action of the light, and the exposed part of the film is then wound upon one spool, whereby fresh paper or film is unwound from the other Eachspool 0 consists of a cylinder of wood or any other suitable material, provided with a triangular, square, or other polygonal or equivalent bore, If desir'ed,the bore may be made circular in cross-section and provided with grooves or notches for receiving splines or keys on the spindle. The spindlesG,fitting in thebores ofthespools O, are made square in cross-section, or have any other cross-section corresponding to that of the bore of the cylinder. As stated above,they are provided with suitable ribs or splines in case they are made circular, which ribs or splines pass into the grooves of the spools to prevent slipping. The upper ends, G, of the spindles are squared to adapt them to fit a key, and below the said squared ends pivot parts G are provided on the spindles, and another pivot part, Giis provided at the lower end, the said pivot parts turning in bearings.

The spindle can easily be withdrawn from the spoolv or passed through the same and into bearings provided for it in the box A. The square parts of the spindles also pass through apertures in wheels H, having serrated or toothed edges, against which springs J rest, for the purpose of preventing the paper from unwinding too rapidly. The said wheels H may be located at the top of the box, as shown in Fig. 1, or they may be at the bottom, as shown in Fig. 7.

The wheels H are not connected with the spools or with the spindles, and are provided with squared. or polygonal apertures, through which the squared or polygonal parts of the spindles pass, or with apertures of any other distance abovethe lower end of the spindle, and the upper end of the spool must be held some distance below the upper end of the spindle. I accomplish this by providing the spindle with two loose collars, L, Fig. 11, the collars having squared apertures through which the spindle can pass, and being also provided with externally squared, straight, or tapered necks M, through which the spindles can pass. Each collar has a screw, N, which can be screwed into apertures O in the spindle, for the purpose of locking the collar on the spindle in the desired place. Thesquarcd,straight, or tapered necks M are forced a greater or less distance into the ends of the spools, and lock the collars on the ends of the spools.

By the use of the abovedeseribed collars on the spindles spools of any size can be held on the spindles at the middle of the same. The spools need not necessarily be bored, but can be made of two or more sections having their inner sides grooved to form a squared or other bore, which sections are then glued together, as shown in Fig. 13.

Where the above-described collars are used the main part of the spindle can be made round, and need not necessarily be made square or polygonal, as the necks on the collars prevent the spool from turning independently of the spindle.

The end of the paper or film c is pasted to the spools, or otherwise secured to the same. The paper or film is wound on the spools, and the said spools on which the paper is wound are merchantable articles-that is, they are to be sold entirely independent of the camera and attachments. lVhen aspool is empty, the spindle is withdrawn from the same, the empty spool is removed, and a filled spool placed on the spindle, and the operation is continued. In a similar manner a spool upon which all the sensitized paper has been wound is removed by pulling out the spindle or drawing the spool oil the spindle, and the filled spool can then be replaced by an empty spool, upon which the sensitized film is to be wound. A

As shown in Fi 5, the spool has a flange or head at each end, which construction is prei'erred, but is not absolutely necessary. To facilitate the removal of the spindles and spools, the upper ends of the spindles are placed in notches T in the top plate, T, of the 130K A, and the said spindles are held in place by springs or latches T", secured on the edge of the top plate, T, as shown in Fig. 9. The top and back of the box A are closed by a removable door, O, having a top flange, 0. The flan'ge O of the said door is provided with apertures 0, through which the upper ends of the spindles G can pass. The door is held in place by pivoted buttons or latches P on th top of the box A.

One of'the rollers D is provided with a winter. 1% whi 11 indicates 011 a raduated l l b circle, It, the position of the paper in front of the partition I]. The paper is marked by periorations produced by a pin on one of the measmarks left by the perforator.

The hinged cover 0* is provided with an opening, It, in one corner, through which the pointer It and its circle are shown, the edges of the opening being provided with a lighttight joint. The partition Eisprel'erably held in place by U-shaped metal pieces \V, the top and bottom arms of which are seen red to the top plate, T, and to the bottom plate of the box A, or to the top and bottom plate of the independent i'rame BI, Fig. 7, which is a frame composed of top and bottom plates connected by the partition F, againstwhich the frame rests, and also connected by the U'shaped metal braces. This frame carries all the interior working parts of the roll-holder, and is made to fit snugly in the light'tight box of the roll-holder, and can be removed therel'rom.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent-- 1. In a roll-holder, a removable bar of wood or other suitable material, T, said bar having notches T, which notches hold the top ends of the spool-shafts in place, substantially as herein shown and described.
